[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the accompanying drawings.

[0025] As Figures 1-5 shown, a novel air cavity adjusting mechanism provided by an embodiment of the present utility model includes a cavity 1, an adjusting plate one 2, an adjusting plate two 3, an adjusting plate three 4, and an adjusting plate four 5. The adjusting plate one 2, the adjusting plate two 3, the adjusting plate three 4, and the adjusting plate four 5 are all slidably attached to the outer wall on one side of the cavity 1. A fixing screw 9 is threadedly inserted into the outer wall on one side of the cavity 1, and a positioning block 7 is sleeved outside the fixing screw 9. Adjusting holes 8 are opened in the interiors of the adjusting plate one 2, the adjusting plate two 3, the adjusting plate three 4, and the adjusting plate four 5, and the positioning block 7 is located inside the adjusting holes 8. Air outlets 11 are provided on the interiors of the adjusting plate one 2, the adjusting plate two 3, the adjusting plate three 4, and the adjusting plate four 5 and on the outer wall on one side of the cavity 1.

[0026] A novel air chamber adjusting mechanism provided by the utility model comprises a cavity 1, a first adjusting plate 2, a second adjusting plate 3, a third adjusting plate 4 and a fourth adjusting plate 5. The first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 are all slidably attached to the outer wall on one side of the cavity 1. A fixing screw 9 is threadedly inserted into the outer wall on one side of the cavity 1, and a positioning block 7 is sleeved outside the fixing screw 9. Adjusting holes 8 are formed inside the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5, and the positioning block 7 is located inside the adjusting holes 8. Air outlets 11 are arranged inside the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 and on the outer wall on one side of the cavity 1. Rotating the positioning block 7 can push the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 to move, and the misalignment degree between the air outlets 11 on each adjusting plate and the air outlets 11 on the cavity 1 can be used to adjust the air volume. When the air outlets 11 on each adjusting plate and the air outlets 11 on the cavity 1 are completely aligned and coincide, the air volume passing through these two air outlets 11 is the largest at this time. On the contrary, when the coincidence degree of these two air outlets 11 is smaller, the passing air volume is smaller. When these two air outlets 11 are completely misaligned and do not coincide, then these two air outlets 11 are closed and no air passes through, realizing the function of air volume adjustment.

[0027] By setting: when the positioning block 7 rotates around the fixing screw 9, the positioning block 7 can push the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 to slide inside the pressing plate 6, so that the misalignment degree between the air outlets 11 on the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 and the air outlets 11 on the cavity 1 can be used to adjust the air volume. When the air outlets 11 on each adjusting plate and the air outlets 11 on the cavity 1 are completely aligned and coincide, the air volume passing through these two air outlets 11 is the largest at this time. On the contrary, when the coincidence degree of these two air outlets 11 is smaller, the passing air volume is smaller. When these two air outlets 11 are completely misaligned and do not coincide, then these two air outlets 11 are closed and no air passes through, realizing the function of air volume adjustment, and solving the problem that it is inconvenient to adjust the air volume of the air outlet 11, resulting in the inability to accurately control the shrinkage situation of the products inside the shrinkage furnace.

[0028] In an embodiment provided by the utility model, as Figure 1 and Figure 2 shown, the number of the first adjusting plate 2, the second adjusting plate 3 and the third adjusting plate 4 is two each, and the first adjusting plate 2 and the second adjusting plate 3 are distributed in an alternating structure.

[0029] In another embodiment provided by the utility model, as Figure 3 、 4 and Figure 5As shown, the air outlet 11 is distributed in an arc triangular structure, and the positioning block 7 is distributed in an arc cuboid structure, so that when the positioning block 7 rotates, it can push the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 to move.

[0030] In another embodiment provided by the present utility model, as Figure 1 and Figure 2 shown, a pressing plate 6 is fixed to the outer wall of one side of the cavity 1 by bolts, and a plurality of sliding grooves 10 are provided inside the pressing plate 6. The first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 are all slidably connected inside the sliding grooves 10, and the sliding grooves 10 can play a guiding role for the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5.

[0031] In one embodiment provided by the present utility model, as Figure 2 shown, the first adjusting plate 2 and the second adjusting plate 3 have the same height, and the third adjusting plate 4 and the fourth adjusting plate 5 have the same height. The first adjusting plate 2 and the second adjusting plate 3 have different heights from the third adjusting plate 4 and the fourth adjusting plate 5.

[0032] Working principle: Thread out a part of the fixing screw 9 from the cavity 1 so that the fixing screw 9 does not squeeze the positioning block 7. At this time, the positioning block 7 can rotate on the fixing screw 9. Rotating the positioning block 7 will push the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 to slide inside the sliding grooves 10. The sliding grooves 10 can play a guiding role for each adjusting plate. When the air outlets 11 on each adjusting plate are completely aligned and coincide with the air outlet 11 on the cavity 1 without misalignment, the air volume passing through the two air outlets 11 is the largest at this time. On the contrary, the smaller the degree of coincidence, the smaller the air volume. When the two air outlets 11 are completely misaligned and do not coincide, the air outlet 11 is completely closed and no air passes through, realizing the function of air volume adjustment, and then accurately controlling the shrinkage of the products inside the shrinkage furnace. After each adjusting plate moves, tighten the fixing screw 9 to hold the positioning block 7 against the side wall of the cavity 1 to fix the positioning block 7. At this time, the two ends of the positioning block 7 can hold different sides of the adjusting hole 8, thereby being able to fix each adjusting plate and prevent the first adjusting plate 2, the second adjusting plate 3, the third adjusting plate 4 and the fourth adjusting plate 5 from sliding by themselves, improving the stability.

[0033] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
